Show confirmation dialog in Fragment

Question

I'm converting my Android application to use fragments. Previously, I had an activity that is now a fragment. Hence, this code can no longer be used:

showDialog(CONFIRM_ID);
// ...
@Override
public Dialog onCreateDialog(int id) {
    // Create the confirmation dialog...
}

From within the Fragment object, I need to show a confirmation dialog that after confirmation throws me back to the object for status update.

E.g.

Inside fragment X.
Show confirmation dialog.
If "yes" update UI for X.

How can I accomplish this? Please provide working sample code.

You can simply create your dialogs (AlertDialog) using the code as shown here: http://developer.android.com/guide/topics/ui/dialogs.html#AlertDialog

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Are you sure you want to exit?")
       .setCancelable(false)
       .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
                MyActivity.this.finish();
           }
       })
       .setNegativeButton("No", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
                dialog.cancel();
           }
       });
AlertDialog alert = builder.create();
alert.show();

If you need to create dialogs with buttons that do not immediately dismiss the dialog itself you can see my answer here: How to prevent a dialog from closing when a button is clicked

Thanks. This will suffice! (But I suspect the best solution is to use `DialogFragment` and somehow propagate the result back to the originating fragment.) — l33t, Mar 18 '12 at 22:03

         AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());       
         builder.setTitle("Your Title");
         builder.setMessage("Your Dialog Message");
         builder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
             public void onClick(DialogInterface dialog, int id) {
                  //TODO
                  dialog.dismiss();
             }
         });
         builder.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
             public void onClick(DialogInterface dialog, int id) {
                  //TODO
                  dialog.dismiss();
             }
         });
         AlertDialog dialog = builder.create();
         dialog.show();
